SOLVED! This Medieval Madness "was" working fine, I addressed all of the previous error messages and for two days it was flawless. Then on the third day it started telling me to check switch 18 "shooter lane" but the switch tests good (with my meter) but tests bad in the "single switch test". During my troubleshooting I also noticed that switch 17 "right return lane" is also testing bad on the "single switch test", however this one isn't showing up in the error report on boot up, just switch 18? I've traced the connections and all check out good, both switches check out with my meter as do the diodes. Can someone make a suggestion as to where I might look next? For all intents and purposes these switches "should" be working.... Thanks.
